It’s a good point, but it is also more complex. For example the severity of policy response tends to be proportional to local severity of the disease. You can imagine a situation where all countries have a different, fixed propensity to Covid, and adjust their policy until they hit some universal level of containment. You’ll then see a world with very different policies but identical outcomes. I think it is hard to disentangle those two in general.
